Yeah, pet peave of mine: not being able to see voltage and current for all supplies simultaneously.  All power supplies should have this ability.

Hi Antoan,

I believe the PS2520/2521 supplies were OEM from GW Instek. The GW PPT-3615
looks identical to my PS2520.
I was never able to scare up a schematic for it, but with the hints and
tips from this EEVBlog repair thread <>
and some persistence, I was able to work through the problems in mine.
Seems the DACs are a weak point in these, plus I had logic supply and
opto-coupler problems with mine.
I'm not super-fond of this supply, the UI is quite horrendous and it can
only display read-back for a single channel at a time.
